My invention relates to cooking ranges preferably of the type in which oil or gas fuel is used,

however the invention is adaptable for use in gcooking ranges employing other kinds of fuel. It is well known that'much energy is-expended by housewives in stooping and lifting during'the operations of inserting, removing, inspecting and turning roasts and the like, being cooked in ranges of the and broiler oven types, and in which the oven burner is positioned in the lower part of the oven. The general object of the present invention is to provide anoven open, at its upper end and provided with a cooking or roasting member or 1 support movable through the open upper endof.

means for automatically venting the hot air from v the oven when the roast support is elevated.

Other objects and advantages of the invention will be apparent as the specification is considered in connection with the accompanying drawing, in which: I Figure 1 is a plan view of a stove for accommodating the present invention;

Figure 2 is a fragmentary plan view partly in section showing oven platform, motor and.

drive gears; Figure 3 is a sectional view on line 3-4 of as Figure 2;

Figure '4 is -a sectional view on line 4 of Figure 2;

Figure 5 is a sectional view on line 55 of Figure 3; and l Figure 6 is a sectional view on line 8-4 of Figure 2.

Referring more particularly to the drawing the numeral i denotes a table top type ofgas range subdivided by a partition wall 2 into a baking oven section 3 and a top burner section 4,- the latter having the usual burners 5, at the top thereof, beneath the grids 6. A two-part cover i hinged to the back of the range closes the top burner section 4 when not in use, while a similar two-part cover 8, is provided for the oven section 3, the latter being open at its upper end as indicated at 9 in the drawing. The usual utility compartments it are provided in the top burner section. while the section 3 is shown as 56 comprising a baking oven, it;is obvious that a swinging burner (not shown) could be employed thus adapting the oven for broiling. I i

Mountedin the oven 3, for vertical reciprocatory movement is a preferably'flat sheet metal member ll adapted to support a roast or the like I abovea set of burners l2. Depending from opposite sides of the member H, intermediate their depth, area pair of arms IS the front edges of which are formed with rack teeth M for engagement withj pinion gears it, carried by a 10 horizontally disposed shaft I 6, extending across the oven 3. Upper and lower guide rollers I! and i! respectively, carried by the arms l3, engage behind guide flanges l! on the side walls 25 of the oven and guide the member H,.as it is ll being elevated or lowered in a manner presently described. Rollers 43 rotatably supported by the side walls of the oven hold the arms in snug contact with the gears l5. Slides 20 are provided at the sides oi! the oven for the reception of pans Q (not shown).

The member H can be elevated to a position flush with the top of the stove by means of an electric motor 22, housed within the utility compartment II and having its drive shaft II connected with the shaft it, through the medium of a friction clutch 24. When the housewife desires to place a roast or other article of food upon or remove'the same from the member II, it is merely necessary to touch a switch button. not shown, to 'start the motor 12, or in emergency this operation may be performed manually by means of a crank (not shown) adapted to engage over a stud ll -on -a bevel gear 28, meshingwith a second beveled gear 21, on the driven shaft l6. When elevated the member II will preferably be positioned flush with the top of the stove and consequently in convenient position to permit of roasting pans being removed from or placed on the support ll without the necessity m ofbending or stooping. Furthermore, in this position the member II can be used as a working surface, or pans containing articles of food can be conveniently slid thereon from the burner section. Any suitable type of two way electric switch 38 is adapted to stop the motor 22 when the member H has reached its limit of travel in either direction,

Experience has proven that hot air trapped in the oven causes considerable discomfort to the o housewife, when it is permitted to suddenly escape at the front of the stove, as frequently happens when the member is elevated to the top of the stove. To overcome this objection means is provided for venting the hot air through t thereof, so that is moved up or down as the case may be, the arm 8| will be rocked on its pivot 84 in an appropriate direction and the vent will be opened or closed, according to the direction in which themember I I is moving. Thus in down position the bifurcation ll of the rocker arm is engagedby the trip member I3 which causes the rocker arm to rotate in an anti-clockwise direction and through link 32, and bell crank II, and to close the damper 29. Converse- 1!, when in elevated position contact 38 engages bifurcation II and moves the rocker arm and damper in reverse'directicns to that just de- 'Ihehinged cover I isadaptedto be automatically raised by mechanism not shown, when the member ll approaches the top of the stove. As this mechanism forms no part oi the present invention further description thereof is deemed unnecessary.

'Ihe movable roast supporting member I I seats upon a pair of coil springs II when the latter has been moved to its lowered position, thus cushioning the shock incident to such movement.

What I claim is: V

i. In a stove having a burner section and a top burner therefor, an oven section at one side of said burner section and having an open upper end in a plane with the upper end of said burner section, a movable cover closing the upper open end of the oven section and adapted to be moved in a position to have a free unobstructed space between the open end of the oven section and the burner section, a burner within the lower end of the oven section, a roast support mounted in said oven section above the oven burners and an area approximately equal to that 01' the open upper end 01' the oven section, and means operated from without the oven for moving said roast support vertically in said oven section to bring the same in a plane with the upper openend oi the oven section and close the same.

2.'Ina stovehaving abumersectionandatop burner therefor, an oven section at one side 01' said burner section and having an open upper end in a plane with the upper end of said burner section, a movable cover closing the upper open end 01' the oven section and adapted to be moved in a position to have a tree unobstructed space between the open end oi the oven section and the burner section, a burner within the lower end oi the oven section. a roast support mounted in said oven section above the oven burners and an area approximately equal to that oi the open upper end of the oven section, a damper for venting the upper end of said oven, means operated by the vertical movement oicthe roast support for opening said damper and means operated from without the oven for moving said roast support vertically in said oven section to bring the same in a plane with the upper open end 01' the oven section and close the same.
